称重智能仪表是电子衡器的一个重要组成部分。为了确保此种仪表的精度及稳定性,新一代称重智能仪表中的信号调理器和电桥的激励源都是精心设计的。美国AD 公司生产的2B31型信号调理器可系统地而不是分散地解决上述问题,它是一个与应变/电阻温度计式传感器直接接口的高精度器件。
Weighing smart meters is an important part of electronic scales. In order to ensure the accuracy and stability of such instruments, signal conditioner and bridge excitation sources in a new generation of weighing smart meters are well-designed. Type 2B31 signal conditioner manufactured by AD Company of USA can solve the above-mentioned problem systematically but not dispersively, it is a high-accuracy device that directly interfaces with the strain / resistance thermometer type sensor.
